Background: Interleukin-2 receptor subunit alpha (IL2RA) is a single-pass type I membrane protein; contains 2 Sushi (CCP/SCR) domains. The interleukin 2 (IL2) receptor alpha (IL2RA) and beta (IL2RB) chains; together with the common gamma chain (IL2RG); constitute the high-affinity IL2 receptor. Homodimeric alpha chains (IL2RA) result in low-affinity receptor; while homodimeric beta (IL2RB) chains produce a medium-affinity receptor. Normally an integral-membrane protein; soluble IL2RA has been isolated and determined to result from extracellular proteolyisis.

Concentration:

Activity: Not validated for activity

Sequence: Glu22-Cys213

Purity: > 95 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from a 0.2 μm filtered solution of 10mM HEPES，50mM NaCl, pH7.2.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
